INQANDESCENT GAS-BURNER. Q

SPECIFICATION forming part Of Letters Patent NO. 617,459, dated January 10, 1899. Application filed January 18, 1898. Serial No. 667,082. (No model.)

the construction of gas-burners used in connection with incandescent bodies or mantles for lighting purposes, and since the said mantles are of a very fragile nature it is found that they necessitate the employment of means to counteract, intercept, or divert any or all jerky or violent vibrations or movements that might be transmitted through the burners and their bearings to said mantles; otherwise considerable loss and inconvenience result from the breakages or damages thereof. Heretofore the means employed for the purpose of counteracting the said damaging movements have consisted of resilient bearings for the burners and their mantles, together with flexible pipe-couplings for supplying the gas thereto, or the metal supplypipe is bent or coiled to afford resilience for the burner and its mantle. However, as'these are somewhat unsightly'their use has been to that that part of same upon or by which the mantle is mounted or supported is entirely carried and every way held by resilient bear ings and that clear of all guiding-pieces or rigid stays, the method of construction followed for this purpose being hereinafter fully described by reference to the accompanying sheets ofdrawings, wherein- Figure 1 is a sectional elevation of a burner constructed in accordance with myinvention, theresilient bearings being arranged on the outside thereof, as hereinafter explained. Fig. 2 is a similar view to Fig. 1, but shows the interior of one part of the burner to be formed in a series of cavities to enable the mixing of the gas and air, as hereinafter described. Fig. 3 is an elevation, drawn to a reduced scale, showing the burner so suspended from or by resilient bearings as it might be within a street-lamp, the latter being shown in broken lines. Fig. 4 is a'simi lar view to Figs. 1 and 2, but shows the resilient bearings within the burners outer part. Fig. 5 is a sectional plan on line A B of Fig. 4. Fig. 6 shows a construction of burner similar on the outside to that shown by Fig. 4, but with the parts within arranged and form ed so that additional inlets for the air are produced. Fig. 7 shows another form whereby the auxiliary air-inlets are produced, while the upper part of the burner is greatly reduced in length. Fig. Sis a sectional elevation showing a style of burner supported by a series of springs and held laterally by same and another series, all of which are desired to be under tension. Figs. 9 and 10 are sectional elevation and plan of an arrangement of burners having their complement of supply-pipes and one spring, with its several other parts to form the resilient supports therefor. Fig. 11 is a sectional elevation showing several burners fed by one supply-pipe and supported by a spring surrounding a certain part of same. Fig. 12 is a part sectional elevation, drawn to a reduced scale, also showing a method whereby one supply-pipe and one spring may be used in connection with several burners. Figs. 13 and 14 are front and side views, also drawn to a reduced scale, showing an arrangement whereby two springs may be used to support several burners beneath them. Fig. 15 is a sectional plan of parts shown by Fig. 4, but with an alternative arrangement of springs to counteract any lateral vibrations of the burner.

Similar letters of reference indicate similar parts throughout the several views.

As is well known, the burners used in connection with incandescent gas-lighting are so constructed as to produce .a Bunsen flame by the admission of air at a certain part of said burner to mix with the gas also fed thereto. The openings through which this air is admitted to mix with the gas have heretofore been formed in the tubular part of the burner, which leads up to where the gas is burned in the Bunsen flame; but in accordance with my invention I entirely separate this tubular part, such as at a, from the upper part Z) above it, so that a clear space a is left between the two, by which means the gas supplied through said part a mixes with the air entering through the open space 0, as indicated by the arrows, and rises to be consumed at the part Z) to render the mantle (Z incandescent, as desired.

The part Z2 is arranged to be supported by the springf, taking underits projecting flange b and resting upon the annular piece g, supported from the supply-pipe a by means of the projections g and pillars g 9 Thus it will be seen that any vibratory or other movements of the pipe a that are transmitted to the mantle d, which'is supported by the rod (1', carried by the part Z), will have to pass through the resilient spring f, by which it is alone supported and by which means the desired counteractions are attained. Instead of the resilient supporting-spring being on the outside of the part Z), as shown by Figs. 1 and 2, it may be arranged to be within it, as shown by Fig. 4, in which case the converging arms are used in place of the flange 11 while should the base of the support afforded said part b be thus brought within too small a space the additional vertical springs h, (of weak or slight construction,) secured at h to the pipe (b, may be employed to counteract lateral vibrations and give the parts alinement; or the arrangement of radiatingsprings 71.2 (shown by Fig. 15) may be employed for this purpose. Again, the part b may be supported by a spring f above it, as

shown by Fig. 3, inwhich case its rods k k reach up to said spring f, which is supported from something entirely independent of the supply-pipe a, such as from the top part of an ordinary street-lantern, which is shown in broken lines, or such superposed support may be the roof of a room or building or the like should said burner be used in such a place or position; or, again, two springs f f as shown by Figs. 13 and 14, may be arranged by rods m m and arms at n to support several parts I) and their mantles d; or a single burner may have a series of springs f arranged around it, as shown by Fig. 8, so that it may be supported from a corresponding series of pillars g while weaker springs 7L3, slightly extended so as just to be in a state of tension, may be arranged to counteract lateral vibrations or movements.

The arrangement shown by Fig. 9 enables one spring fto support a part 12 having a number of incandescent parts mounted upon it, while a number of supply-pipes a are employed; or one supply-pipe a may answer for one part b upon which a number of incandescent parts are mounted, as shown by Fig.11. In this case also only one resilient supporting-spring f is employed; or this arrangement may be reversed and one supplypipe CL may be enlarged and have a number of outlets a supplying a like number of separate parts I), as shown by Fig. 12, and in this case also only one supporting-spring f is employed for the whole series.

The construction of burners by one part being separate from the other, as above described, enables a formation whereby openings'for the admission of air for mixing with the gas maybe made in more than in one position, as shown at 0, c and c by Fig. 6 or at c and c by Fig. 7. In this latter figure the part b is shown considerably shorter, compared with the sizes of the other parts, than it is in the other figures, which shows that I am perfectly aware that its dimensions in any direction may be varied to meet the requirements or tastes of the producer or user.

It is thought that the mixing of the air with the gas may be improved by forming the passage through the part b in the shape of a series of cavities, as shown by Fig. 2, such cavities gradually increasing in size from the one at the bottom to that at the top.

To prevent particles of dust or foreign matter from being carried by the currents of air to enter these burners, a gauze shield 17 is employed and arranged to encircle the openings c, as shown by the several figures.

In order to make the mantles flt nicely over the upper ends of the parts 1), these latter are made of a tapering shape, somewhat as shown by Figs. 7 and 8, while an annular'flange s is formed about same to protect the lower edge of the mantle d from the actions of inrushing air. In Fig. 8 the flange s is shown as being detachable and formed to carry the rod d and its mantle d, by which means said parts may be readily removed from the part b to allow repairing or cleansing operations to be carried out.

Referring to Fig. 6 of the drawings, it will be noticed that a shoulder or collar is represented as carried by the gas-pipe a little below the broken-out portion. This collar or shoulder may be employed to support arms or projections, such as shown at g in Fig 1, and a shield, such as shown at p in said figure and in other figures. Springs such as shown at h in Fig. t or as indicated at 7L2 in Fig. 15, may obviously also be employed in connection with the construction shown in Fig. 6.

' Such being the nature and object of my said invention, what I consider new and claim is- 1. In an incandescent gas-burner, a gaspipe, a tubular member surrounding the ori fice thereof, the interior of said tubular member constituting a mixing-chamber whose airinlet is the annular space between the gaspipe and the tubular member, a m antle-holder attached to said tubular member, and resilient supporting means for said tubular member.

2.
